A new lightweight polyethylene collecting drainage outlet is introduced after analyzing of the drainage outlet project materials and the results of the field tests of various outlet constructions. The standard design of the drainage outlet is worked out and brought into the service. Comparative analysis of the designed outlet and other spillway flumes (asbestos-cement, polyethylene and reinforced concrete pipes) is made. Characteristics of different connecting sleeves are presented. Technical characteristics of new lightweight polyethylene collecting drainage outlet (ceramic pipes) are displayed. Developed outlet is light, easy to work with and it does not require special equipment to construct it. The reliability of a structure is ensured by the use of high-strength polymeric materials used in the construction of the components. The unit value appears to be 25 USD less than the previous models and the working efficiency while constructing rises by 1.7 times. Economic rate equals 750-1250 USD per every 100 ha reconstructed with the developed lightweight drainage outlets.
